Method of Driving Light Emitting Diode Backlight Unit and Display Device Performing the Same

5. The backlight driver of claim 4, wherein at least one of a starting time point, an ending time point, or a length of the first high-impedance interval is changeable.

7. The backlight driver of claim 6, wherein a starting time point, an ending time point, and a length of the second high-impedance interval are same as a starting time point, an ending time point, and a length, respectively, of the first high-impedance interval.

8. The backlight driver of claim 6, wherein at least one of a starting time point, an ending time point, or a length of the second high-impedance interval is different from at least one of a starting time point, an ending time point, or a length, respectively, of the first high-impedance interval.

14. The backlight driver of claim 13, wherein the first switch is closed during the high-impedance interval based on the source high-impedance timing.
